Thermoplastic polyurethane (TPU) is a type of polyurethane plastic with a number of significant characteristics, including flexibility, transparency, and resistance to abrasion, grease, and oil. Due of its extraordinary flexibility, it is distinctive. TPUs are technically formed of thermoplastic elastomers. However, because acids, solvents, and fuels can alter their properties, it is preferable to keep them apart.

Various varieties of TPUs are commercially available, depending on the use;

• Polyester-based TPUs, which are derived from adipic acid esters,
• Polyether-based TPUs, which are derived from tetrahydrofuran ethers,
• Polycaprolactone-based TPUs, which are derived from thermoplastic polyurethane elastomer.

TPU offers a variety of benefits, including rubber-like flexibility, abrasion resistance, low temperature performance, elasticity, and mechanical qualities. Consider flexible TPU as a material that is a combination of silicone and hard plastic.

Caster wheels, instrument panels for automobiles, sporting goods, power tools, medical equipment, footwear, drive belts, inflatable rafts, and several more extruded film and sheet applications are among the main uses for TPU. TPU is a good material to utilize for mobile devices’ outer casings, including those on tablets and phones. It has been stated in a study that was published in the journal Sensors that TPU can also help in coating antennas for effective performance even after several wash cycles. TPU is an excellent thermoplastic elastomer that bridges the gap between plastic and rubber. It is robust and durable.
